Answer:
59 arc minutes
Step-by-step explanation:
Given measurement,
1.98 degrees
We can write,
1.98 degrees = 1 degree + 0.98 degree
Now, the number of arc minutes in 1 degree = 60,
So, the number of arc minutes in 0.98 degree
= 0.98 × arc minutes in 1 degree
= 0.98 × 60
= 58.8
≈ 59.
Hence, 1.98 degrees is equal to 1 degree and 59 arc minutes.
